All the SRPMs are provided. All the git trees (with logs) are provided. All the binaries are provided. All the mock configs will be provided. All the build logs will be provided. People will be able, if they choose, to check out any portion of the code and modify it on their own. Things with mods that are needed for SIGs can be pushed back into that SIGs tree and be part of the project. CentOS will not be publishing RHEL packages directly, we will be publishing (like we do now) the things that come out of the build system ... which are tied to the build logs, root logs, and source code that will be published. Everything will be available for public community review ... in fact, I would personally be suspicious of anyone who wanted to take the code and rebuild it OUTSIDE this openness, since all the source code, build logs, git tree history, etc, will not be available for that rebuild (or if it is available, then it is completely duplicated effort). Instead, if those people concentrate on what it is that they want to be different from the BASE, then anyone that wants to use what they produce, THAT IS DIFFERENT, can choose to get it. All of the community wins by getting more things that work with the EL code base ... rather than silos (or stovepipes) of things that are the same. -------------- next part -------------- A non-text attachment was scrubbed...
